S/4HANA Migration & Clean Core

Build a migration roadmap from your own verified data — the countdown that actually matters, what Clean Core really means, reading a readiness score, remediating without over-building, and the data-quality trap that ambushes cutover.

    Lesson

    Why 2027 Isn't a Deadline — It's a Countdown Already Running

    Lesson 1 — Most teams treat the ECC end-of-mainstream-maintenance date as a distant line on a slide. It isn't distant, and it isn't really about that one date at all. Here's the countdown that's actually running, and why it started already.

    What Clean Core Actually Means (and What It Doesn't)

    Lesson 2 — Ask five consultants what Clean Core means and you'll get five different answers, and at least two of them will be wrong in a way that costs a client real money. Here's the precise definition, and the trap hiding in the word 'clean.'

    Reading Your Own Risk: The Readiness Assessment

    Lesson 3 — A client asks 'how bad is it, really?' and the honest answer requires a number you don't currently have. Here's what a readiness assessment actually measures, and why the score matters less than what's underneath it.

    Lesson

    Remediation Without Rewriting Everything

    Lesson 4 — The instinct after seeing a scary readiness report is to rewrite everything from scratch. That instinct is how a six-month project becomes an eighteen-month one. Here's the actual remediation hierarchy.

    Data Migration: The Part Everyone Underestimates

    Lesson 5 — Code remediation gets the attention because it's visible in a scan report. Data quality problems don't show up until cutover weekend, when they're the most expensive possible time to discover them. Here's how to find them early instead.

    Capstone: Building Your Own Migration Roadmap

    Lesson 6, the capstone — Everything in this journey lands here: a real roadmap, built from your own readiness data, that survives contact with a steering committee instead of just a slide with a countdown on it.
